Pros
If this is your first opportunity to get into pentesting - this is gold! You are very unlikely to find a better place to learn and gain experience. The mid-senior-expert colleagues are for the most part extremely overqualified and very open to teach, mentor and support you on your journey. People in AppSec are definitely the biggest and one of the only "pros" that make this job worth it.
Cons
1. The wages here aro not low, they are well below any averages. 2. There seems to be an increase in micromanagement, lessening in the opportunities for any possibility of remote/hybrid work. 3. The benefits have deteriorated or simply taken away due to "budget cuts". 4. A lot of clueless people in management, sales and customer success positions that have absolutely no merit to hold them. 5. Overall, the management seems messy and very much "valuation-oriented". 6. There's very little room for actual progression in the career and the differences between junior-mid-senior-expert are very unnoticeable. 7. If you are promised something or something is mentioned as a benefit during your hiring process - demand it to be listed in the contract so they won't back out. 8. No paid overtime.
